Hi; Drosophila melanogaster I'm a student at molecular biology and genetic 2.Class. In genetic labratory I crossed Scarlet Female and White male. As I search and find it ; There two gens at Drosophila : bw+ for brown , st+ for red. bw+st+ is wild type. I crossed Scarlet And white so my genotips are ; Female bwbw st+st+ Male bwbw stst But my f1 is with brown eyes, and scarlet eyes, I have no idea about how to explain it . Would some one help me please? What is the molecular pathway of drosophila's eyes when we cross white and scarlet my F1: Brown and Scarlet my f2 : White Brown Scarlet And Red
I don't do a lot of ordinals and a lot of my background is bloody outbreds. Can you tell me whether the source scarlet-eye and white-eye strains are reckoned to be 'fixed' for eye colour genotype? (That is, homozygous within each line.)
Hi for Scarlet : BwBw St+St+ For Brown Bw+Bw+ StSt For White : Both gens knock-out : BwBw StSt Bw gens are on the 3rd chromosome, St gens are on the 2nd. My Scarlet Female was virgin and homozygous, my white male was Homosygous too.
